Sanitary Device Data Retrieval Using Proximity Request Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing and retrieving sanitary device data in a cloud environment face challenges in ensuring pseudonymized data security, as they either expose sensitive data to unauthorized access or fail to identify the rightful owner, allowing impersonation.
Innovation Solution
A method involving a terminal device, sanitary device, and network device that uses pseudonymized data storage, where the terminal device sends a first data request with identification information, the sanitary device sends a second request upon notification, and the network device compares these requests to authorize data transfer to the terminal device, ensuring proximity and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sanitary device data is stored in a pseudonymized form on a network device, then data privacy and security are improved, but it becomes unclear who has access to the data, allowing unauthorized third parties to impersonate the owner
Solution Approach 1:
The patent introduces a network device as an intermediary between the terminal device and the sanitary device. The network device receives the first data request from the terminal device, generates a second data request, compares the two requests, and only provides access if they match. This intermediary mechanism enables pseudonymized data storage while maintaining secure access control without requiring direct user identification.
2Ease of operation
If a user account system is used to access sanitary device data in the cloud, then data retrieval is simplified, but sensitive data may be disclosed to third parties in case of unauthorized access
Solution Approach 1:
The patent extracts the user account identification mechanism from the data storage system. Instead of storing data linked to user accounts in the cloud, the system uses pseudonymized data with no direct user association. The terminal device still needs to provide identification information, but this is verified through the request comparison mechanism rather than through user account authentication, thereby removing the vulnerability of stored user credentials.
3Reliability
If pseudonymized storage of sanitary device data is implemented, then data privacy is improved, but it is not possible to clearly identify the rightful owner of the data
Solution Approach 1:
The patent uses identification information as a copy or representation of the owner rather than storing direct owner identification. The terminal device provides identification information that serves as a proxy for owner verification. The network device compares this identification information with the second data request to verify ownership without needing to store or expose the actual owner identity, thus maintaining privacy while enabling verification.

AI summary
A method for retrieving sanitary device data using a terminal device, preferably a mobile terminal device, is provided wherein the sanitary device data is stored in a pseudonymized form on a network device, preferably in a cloud network, wherein the sanitary device data contains information about a sanitary device, comprising the steps:the terminal device makes an initial data request;the sanitary device makes a second data request after receipt of a notification from the terminal device of at least one intended instance of the first data request being sent;the network device compares the first and second data request;the network device provides the sanitary device data to the terminal device based on the comparison of the first and second data request;the terminal device calls up the sanitary device data.
